The composting toilet setup aboard Floating Empire
Our toilet is simple: We have a 5 gallon bucket. We cut off the top rim of it so it would sit inside ANOTHER 5 gallon bucket. So the top 1/3 or so bucket is affixed to the toilet box cover and the lower one sits below, kept aligned to the upper one by the nesting design of these things. This also keeps the liner in place.
The cut off half bucket...okay, so I was a little jagged. The fitting is from the urine diverter that we ultimately decided we didn't need. The rim of the upper bucket keeps it from popping through the plywood and it's taper keeps it nested in its lower cousin. Apologies for my arm being in the way, but I had to hold the thing open somehow.....
Here's the snap on toilet seat from LuggableLoo. You can also see the upper and lined lower buckets.
Whenever you use the toilet, you throw in a handful of absorbent material. We've used crushed dry leaves, sawdust (not from treated lumber....it inhibits the decomposition process), pine based cat litter (don't use the clay stuff), and wood stove pellets. As long as you throw in enough to lightly cover what you just...uh...left, there's no odor except one of damp wood. No, really, it doesn't smell. It doesn't. Not at all. My Cat box smells more than the toilet does.
When the lower container is 3/4 full, we pull it out and either put it in the compost bin or throw it in a dumpster (can you do that? What do you think happens to all those disposable diapers?). The last time I tossed it in a dumpster, the bag broke. It looked like a pile of wet oatmeal, no odor but one of decomposing wood, no loose liquids at all.
So then you reline the lower bucket, toss in another 2" of material, and you're ready to continue. With the two of us living on the boat, we dump the thing about every 5 days or so.
As for the biomass, our big accidental find was the hardwood pellets for pellet stoves.
Yes, these things. Compressed hardwood sawdust made for pellet stoves.
Seriously, folks, this is the absolutely easiest way to deal with your leavings and to meet Coast Guard regs.....
and, really...it doesn't smell.
